The Eclipse Memory Analyzer has been shipped with Eclipse 3.5 Galileo and I planned to start a new series here about memory usage antipatterns and how to analyze them with MAT.
Unfortunately I'm pretty busy these days and I will need more time for those posts.
But, due to popular demand I decided it would make sense to post some good links (ok, I admit some of them are from myself) about how to use the Eclipse Memory Analyzer.
Please forgive me if I missed some important ones, but I'm really hungry now and therefore just stopped after 10 tips ;)
